She's awake!

[wolfman]

Well, after 5 months, I put her fresh "clothes" on and charged the battery. ?A fresh tank (drained for painting) of fuel with a 1/2 bottle of Gumout added (carbs were drained over the winter). ?"Prime" for about 2 minutes and the full choke. ?Within about 10 secs of cranking she came to life. ?Settled into an idle of sorts. ?Warmed normally etc... ?62 miles in the last 2 days. She now starts, idles and runs just fine.?Two things of slight concern to me though. ?The coolant in the resevoir was down noticeably from where it was when parked, but went right back up after the bike started (not after it had warmed, just started) ?I also have an ever so slight intermittant trickle out the waterpump weep hole. ?I can remember it did this before after another extended sleep, but stopped within a week or so of regular use. ?Should I be worried? ?(NO noticeable coolant level drop, or visable drips or puddles, she just drops a drip or two right after I shut her down and that it. ?It DOES NOT weep when running.)

Sounds like you might have a little bit of air in the cooling system, also might be a little leak at the waterpump seal. The coolant level in the 'catch tank' should not get higher until the engine has reached operating temp when the expanded heated coolant runs into it. The catch tank level then drops when the engine is shut off as the coolant cools and contracts and draws the excess back in to the system.
 I think the drips from the weep hole indicate a bad water pump seal. It may not be critical now but will probably get worse. The seals are available from Yamaha.

When you replace the  water pump seal , be sure to replace the seal in the outer case that the crank end goes into. It transfers oil to the crank and rods , if it fails you WILL lose a rod bearing.
